ruimen

noun. fireplace, hearth

A word for “fireplace, hearth” in 1964 notes on Dalath Dirnen (DD) derived from the root √RUYU “blaze, red” (PE17/183). Its second element might be √MEN = “place” (its meaning from the 1930s), though in Tolkien’s later writings this root was more often used for “direction”.

Conceptual Development: Earlier fireplace words from the Qenya Lexicon and Poetic and Mythological Words of Eldarissa of the 1910s include ᴱQ. arin “hearth” derived from the early root ᴱ√ARA “be dry” (QL/32; PME/32) and ᴱQ. purin (purind-) “hearth” derived from the early root ᴱ√PUŘU [PUÐU] “consume by fire” (QL/76; PME/76).

ruist

noun. fireplace, hearth

A word for “fireplace, hearth” in 1964 notes on Dalath Dirnen (DD) derived from the root √RUYU “blaze, red” (PE17/183).

Conceptual Development: The Gnomish Lexicon of the 1910s had G. tangar or tangor “hearthgrate, fireplace” based on the early root ᴱ√tan- (GL/69). Gnomish Lexicon Slips modifying that document had G. bordd [borð] “fireplace” related to primitive ᴱ✶búrı̯ā (PE13/116). Early Noldorin Word-lists of the 1920s had ᴱN. {borth, bordh “hearth” >>} gorth “hearth, fireplace” (PE13/139, 145).
